This is post 2495 in a continuing series of simple ham radio antennas.

If you have space limitations, a top-loaded vertical antenna may solve your radio problems.  Coupled with a good ground system, a top-loaded vertical can perform quite well.

In this video, Australian ham Peter Parker (VK3YE) erects a simple top-loaded vertical over the ocean and gets some great contacts.

Here are some comments from Peter:

Don't have much height but have something metal underneath? If so a top loaded vertical is a great antenna to try. Just 10 metres wide and 5 metres tall it will even load up on 3.5 MHz. Especially if you're over salt water, you're unlikely to get anything better for its size. The key items needed include wire, two poles, a simple antenna coupler (an L-match is fine), something to clip onto the counterpoise railing and a ground tuning unit. I'll probably describe a more refined version later but it comprises a variable capacitor in series with an inductor. It's also desirable to have an RF current indicator. PS: Like these videos?
